Question 683474
x = 164 - y
z = 90 - y
so
y + 90-y + t = 184
90 + t = 184
t = 184 - 90
{{{highlight_green(t = 94)}}}
...
then
164-y + y + 90-y + 94 = 294
164 + 90 - 94 - y = 294
-y = 294 - 160
-y = 134
{{{highlight_green(y = -134)}}}
...
x+y = 164
x + -132 = 164
x = 164 + 132
{{{highlight_green(x=296)}}}
...
y + z = 90
-134 + z = 90
z = 90 + 134
{{{highlight_green(z=224)}}}
